Vegetation - Mojave Desert for DRECP - Final [ds735]

Aerial Information Systems (AIS) and the California Department of Fish and Wildlife (CDFW) Vegetation Classification and Mapping Program (VegCAMP) with assistance from the California Native Plant Society (CNPS) created a fine-scale vegetation map of portions of the Mojave and Colorado Deserts in California. Approximately six million acres spanning desert portions of Inyo, Kern, Los Angeles, San Bernardino, Riverside, and Imperial Counties were mapped between 2011 and 2012. In addition, mapping of 95,981acres within a portion of Rice and Vidal Valleys in the Colorado Desert portion of the Sonoran Desert was completed by AIS in 2013‐2014. The maps were primarily produced to support the Desert Renewable Energy Conservation Plan (DRECP) by helping planners more accurately identify high quality habitat and rare communities as they consider renewable energy sources and conservation opportunities. Previous vegetation maps of the area were either large scale and generalized or they were detailed but covered a limited extent. Between 2014 and 2016, as an extension to supplement those mapping efforts, AIS was tasked to create a fine‐scale vegetation map of 2,195,415 acres of desert in Inyo, San Bernardino, Riverside, and Imperial Counties in southern California. Areas mapped include the eastern and central portions of the Mojave Desert as well as the Lower Colorado Valley, also referred to as the Colorado Desert, and the Arizona Upland subdivisions of the Sonoran Desert.The vegetation classification follows Federal Geographic Data Committee (FGDC) and National Vegetation Classification Standards (NVCS). The classification is based on previous survey and classification work. The map was produced applying heads-up digitizing techniques using a base of true-color and color infrared 2010 or 2014 one-meter National Agricultural Imagery Program (NAIP) imagery in conjunction with ancillary data and imagery sources. Map polygons were assessed for Vegetation Type, Percent Cover, Exotics, Development Disturbance, and other attributes. The minimum mapping unit (MMU) is 10 acres; exceptions are made for wetlands and certain wash types (which were mapped to a one or five acre MMU) and areas characterized as Land Use polygons (which were mapped to a 2.5 acre MMU). Field reconnaissance and accuracy assessment enhanced map quality. A total of 68,992 map polygons representing 154 vegetation map classes were developed.
